Analysis of straight flange on pressure vessel head
(OP)
Is there a published ASME "opinion" that the straight flange of a pressure vessel head does not have to be designed as a shell element? APV software does not include the straight flange in the head analysis but Compress appears to do so.

After all, it is a shell element up to the tangent line where the shell becomes a head. Thus the reason for the 3:1 tapered transition per UW-13.1 as well as provisions in UG-32(l) only when the formed head is thicker than the shell, concave to pressure and intended for butt welded attachment
Parsed from UG-32(l)..........All formed heads concave to pressure and intended for butt welded attachment need not have an integral skirt when the thickness of the head is equal to or less than the thickness of the shell......
